The Stellar Development Foundation partnered with PwC US to create a framework for assessing blockchain protocols' electricity consumption and greenhouse gas emissions. The guide addresses CBDCs' potential for financial inclusion, interoperability, and sustainability on open networks.

The Stellar Development Foundation has released a comprehensive guidebook developed in collaboration with PwC US that introduces the first-of-its-kind assessment framework for measuring electricity consumption and greenhouse gas emissions of blockchain protocols. The guide is designed for central bankers and policymakers evaluating Central Bank Digital Currencies (CBDCs), emphasizing how CBDCs can improve financial inclusion and benefit unbanked and underbanked populations. Key topics covered include cooperation between public and private entities, the importance of open blockchains for security and equal access, CBDC interoperability for cross-currency transactions, and critical characteristics to prioritize including sustainability, reliability, and programmability. The framework provides a holistic view to help blockchain and financial services organizations measure their environmental footprints while advancing SDF's vision of an 'internet of money' that makes payments as accessible as email.
